library(curl)

# Verbose
h <- new_handle()
handle_setopt(h, verbose = TRUE)
req <- curl_perform("http://httpbin.org/get", handle = h)

# Parsing headers
parse_headers(req$headers)

# Streaming with a callback function:
get_with_callback <- function(url, cb){
  con <- curl(url)
  open(con, "rb")
  on.exit(close(con))
  while(length(buf <- readBin(con, raw(), n = 8000))){
    cb(buf)
  }
  invisible()
}
